TUBING COMPANY, or HoN snALE, PENNSYLVANIA FLYER TWISTING FRAMEApplication filed August 15, 1928. Serial No. 299,837.

This invention relates to spinning and chiefly to the twisting mechanismof the type embodying a flyer twister frame, the purpose being toprovide for the ready removal and replacement of the flyer, yetpreventing casual displacement of the flyer from the spindle should itbecome loose.

The invention contemplates a. novel form of flyer includinga hub, orblock formed with an annular groove, and a two armed flyer having itsmiddle portion fitted in the annular groove of the hub and retainedtherein by means of two oppositely disposed pins.

While the drawing illustrates a preferred embodiment of the invention,it is to be understood that in adapting the means to meet specific needsand requirements, the design may be varied and changes in the minordetails of construction may be resorted to within the scope of theinvention as claimed, without departing from the spirit thereof.

vFor afull understanding of the invention and the merits thereof,referenceis to be had to the following description and the drawins;hereto attached, in which igure 1 is' a longitudinal, central, sec- Vtional View of a bobbin and flyer twister embodying the inventionshowing the same mounted upon a spindle.

Figure 2 is an enlarged fragmentary, sectional view at a right angle toFigure 1 of the flyer and adjacent end of the bobbin.

Figure 3 is a detail sectional view on the line 33 of Figure 2 lookingin the direction of the arrows.

Figure & is a detail sectional view onthe line 1-4L of Figure 2 lookingin the direction indicated by the arrows.

' Corresponding and like parts are referred to in the followingdescription and designated in the several views of the drawings by likereference characters.

The numeral 1 denotes a spindle of a fiyer twisting frame and 2designates the body of the bobbin which is adapted to slip upon thespindle 1 and engage the same frictionally so as to rotate therewith. Arecess 3 is formed in the upper end of the bobbin 2 and receives thereduced portion 4 of a cap or head 5. Screws 6 or analogous fasteningssecure the cap to the body of the bobbin 2. r The cap or head 5 isformed with a central opening in which isfitted a collar 7. A flange 8projects inwardly fromthe outer end of the collar 7. The collar 7ispressed into. the opening 3 and retained therein by frictionalengagement. Thetwister'comprises a hubor block 10 formed intermediateits ends with an outer enlargement'll and at its inner end with aneccentric flange 12 of a diameter to pass" snugly through the openingdefined by the inner flange 90f the collar 7 The outer enlargement llisformed with an annular groove 13 in which isfitted a curved portion14=of the flyer." The hub or block 10 is formed with an opening to receivethe spindle 1. vi W M' The'flyer includes two arms -l'5 wh'ich constitute end portions of a wire, the middle portion of which is bentintosemi-circular form, as indicated at 14, to snugly; fit within theannular "groove13 and about the hub-of thetwisterg; .Pins "16 extendacross the annular groove 13 and their ends are supported in the partsbordering upon the groove. The pins 16 are disposed in the angle formedbe tween the arms and the semi-circular portion 14: of the flyer. Thearrangement admits of ready replacement of a broken or crippled flyer aswill be readily comprehended.

As shown most clearly in Figure 2 of the drawing the flyer is centeredwith reference to the bobbin by means of the spindle 1, hence ingopening enlarged at its outer end, a flange projecting inward from thebobbin across the enlarged portion of the spindle receiving opening, aflyer, and a flange projecting outwardly from the flyer and overlappingthe flange of the bobbin to prevent outward displacement of the flyer,the parts being nor:

loo

mally held in operative position by means of the spindle.

2. In a flyer twisting frame, the combination with the bobbin, andflyer, of a flange projecting inwardly from the bobbin, and a companionflange rojectingoutWar-dly from the flyer, the two anges b'eingh'eld ingiven position by means of the spindle.

3. In a flyer twisting frame, the combination with the bobbin, a capsecured to the outer end of the bobbin and having a central opening, acollar secured within the opening of the cap and formed with an inwardlydisposed fiange, and a flyer formed with an eccentric flange adapted toenter the said collar and overlap the flange thereof, the parts beingheld in operative position by means of the spindle. v

4:. .In a flyer twisting frame, the combine- -30 tion of a bobbin, a capat the outer end thereof provided 'With ac'entral opening, a

collar within the opening of the cap and having an inner flange at itsouter end, and a flyer'hav'ing an eccentric flange at its inner endnormally disposed within the said collar and overlapping the innerflange, thereof to prevent accidental displacement of the fiyer whichnormally is held in given position means of the spindle.

5. n a flyer twisting frame, a bobbin, an annular flange thereon, aflyer, and aneccentric flange on the flyer to coact with the'flang'e ofthe bobbin and retained in cooperative position by the spindle when thebobbin and flyer are mounted thereon to prevent accidental displacementof theflyer.

In testimony whereof I aflix my signature.
